GCC 11.3 vs GCC 12.3

[CTabo.1]

Hello,
I am going to start a new project on a STM32H5 microcontroller, and first I have updated the STM32CubeIDE to the latest version v.1.14.0.

I have seen that the default toolchain is still v.11.3, but that is also possible to install the new v.12.3.

Which GCC version is better to choose for the new project? Should I mantain 11.3 or pass to 12.3?

Best regards,

Carlo

If you have no reason to choose one over the other, stick with the default to make your life easier.

All versions of GCC are stable. Newer versions typically implement new features in the latest C++ standards, which you are unlikely to be using on a microcontroller project. Check the release notes to know the differences exactly.
